Be iE known Ehat I, ALBERT E. BAUM, a ciEizen of Ehe Unitecl States of America, anal a resident 0f VVaEerloo, Blackhawk county, 10wa, have invenEeal cerEain new anal useful Improvements in DoughnuE-Cutters, 0f which Ehe follwing is a speeification.

My invention relates Eo improvemenEs in doughnuE-cutters; anal Ehe objecE of my inven- Ei0n is Eo provide means whereb5 alough may be shaped inEo Ehe requireal confi'guraoion anal porEions Ehereof cuE from Ehe original mass and withouE interference EherewiEh alroppeal inEo Ehe recepEacle plaeeal Eo receive Ehem. This objecE I have aecomplisheal by Ehe means which are hereinar'ter aleseribeal anal claimeal anal which are illustrateal in Ehe drawings hereEo annexeal anal in which Figure 1 is a sicle elevaEion of my' improvecl cake-cutter. Fig. 2 is an encl elevaEion Ehere- 0f. Fig. 3 is a bottom plan view Ehereof, anal Fig. 4 is a detail view of Ehe cam anal reciprocating meehanism.

Horizontally-alisposed corrugaEed drums 7) anal 0 are mounteal parallel Eo each 0Eher 0n Ehe shafEs 71/ anal Z, pivoEed in bearings WiEhin anal between Ehe side plaEes (Z anal e 0f Ehe machine. These drums are causecl Eo roEaEe inwarally Eowaral each 0Eher by means 0f Ehe intermeshing gears in, m, anal Z, Ehe pinions n/ anal 0, anal Ehe crank p.

The shafE 0 013 Ehe pinion 0 extencls Ehrough bearings in Ehe siale plates (Z anal anal is furnished WiEh a bevel-gear q WiEh which Ehe bevel-pinion 7 intermeshes. The shafE 25 of Ehepinion 0 is rotatable within bearings in Ehe brackets e* anal e anal has aE iEs lower enal a cam-wheel u,whose lowersurface has a pin u. A hook resEs upon Ehe upper snrface of Ehe eam-wheel u, anal its long arm is riclalen by a fork w, whose inner end has iEs upwarclly-exEenaling sEual m pivoteal Eo l a sEual on Ehe brackeE The sEual u on Ehe carn wheel a extenals downwarally inE0 anal works WiEhin a longitudinal sloE in Ehe forl m. AE Ehe enal ot' Ehe long arm 0f Ehe h0ok m is placeal an upwaral-extenaling block w, E0 which is lixeal 0ne end 0f a bow w, carrying a wire cutter w.

When in use, Ehe maehine may be gu ialeal over any portion of a pan placeal beneaEh iE by means 0f Ehe handle ;2 When a supply of alough has been placeal in Ehe hopper a anal Ehe crank p is Eurneol, Ehe corrugated surfaces of Ehe clrums b anal 0 caEch anal alraw iE al0wn between Ehem anal force iE inEo a eompartmenE contained between Ehe side plates (Z anal 0 anal Ehe slanEing enal plates g. The npper ealges of Ehe enal plaEes r nearly approach Ehe surfaees 0'f Ehe corrugateal drums Z anal c, anal Ehus aeE as scrapers, keeping Ehe alough l:'ron1 exuding fr0rn Ehe eontaining-ehamber. Tl1e saial enal plates are maale removable for Ehe purpose of cleaning anal when in place are retaineal by means of Ehe hooks g connecteal Ehereto, whieh eng-age Ehe projections h 0E Ehe bottom plate /2. The dough being under compression in saial compartment is forceal downwaral between Ehe dief and hollow tramcaEecl con@ J where iE acquires Ehe alesirecl configuraEion. The rotation 0f Ehe crank p causes Ehe bevelgear Eo rotaEe Ehe cam-wheel u. The sEual u working within Ehe sloE in Ehe fork m causes saial fork Eo move on iEs pivoE :1: anal wiEh iE Ehe hook m. The bow w anal iEs euEEer w are Ehus reciprocateal aeross Ehe lower surface cf Ehe conef. The spring A handle l/ is pivoteal beEween Ehe outwardly- 2) prevents the cutter w from contacting With the eone f. The short arm 0f the hook w rides upon the upper part cf the cam-wheel u. This short arm moves upon and is supported by the higher part 0f the cam-surface during that part 0f the latters revolution when the cutter w is being horizontally reciprocated 0ver and close to the lower surface 0f the cone f. As a result cf the continued revolution 0f the cam-wheel u, es shown in Fig. 4., the short arm cf the hook x drops 110 the lower portion 0f the cam, which results in a lowering cf the block with its bow w and cutter w. This position cf the cutter is mainoained during that pori0n cf Ehe revolution 0f the cam-wheel u where said cuoter is being reciprocatcd back t0 its first position. This dropping cf the cutter w during its return movernent is necessary in order -t0 prevent its coming in contact with the dough exuding through ube cone f. As the cutter w euts 0ff a portion 0f the dough said porbion drops edgewise into the hot grease in the pan, and a slightdisplacement cf the position cf the n1achine puts it into a new position f0i the deposition 0f a fresh portion.

This machine is constructed in the abovedescribed method and suspended on a brackethanger in order t0 particularly adapt it for use in cutting and dropping doughnuts into the pans cf boiling grease set thereunder. 113 is weil known that if such portions 0f dough are placed in a pan and the grease poured over them the cakes Will stick t0 Ehe b0ttom cf the pan and burn there, and, on the other band, if the cakes are first powdered With fiour before being deposited in the pan the flou1: burns and covers the cakes with an unsightly coating. The macnine which is hereinbefore described is the only one wbieh can obviate either cf the seid objections,inasmuch as i cuts 0fl" the portions and drops them directly into the boiling grease in the pan without the necessity for a powdering of flou1, and by reason 0f the adjustable hanger enables the machine to be shifted from side to VVhile I am aware that machines have been k constructed which will sever portions of a viscous substance and drop them on a receptacle er carrying-surface, yetI maintain tha'n for the proper deposition cf the portions cf dough Clli5 01f f0r doughnuts and their regular distribution and submergence in the b0iling grease underneath the eombination 0f elements shown accomplish a new and useful function and one attainable in n0 other way.

Having described my invention, wha1; I clairn as new, and desire 130 secure by Letters Patent, is

1. A doughnut-cutter, consisting of a die, rneans f0l forcing dough therethrough, a camwheel, means for rotating said cam-wheel, a reciprocating cutter,rneans whereby seid camwheel may recipro cate seid eutter close 130 the surface of said die on its cutting stroke and farther away therefrom 0n its return stroke, and means f0i' varying the position of the whole machine, substantially as shown and described.

2. Adoughnut-cubter,consisingofafrarne, a die berein, corrugated drurns mounted over said die adapted force dough therethrough, n1eans for rotating said dru1ns, a cam-wheel, means for rotating seid cam-wheel, a recip rocating cutter, means whereby said camwheel rnay reeiprocate said cutter close to the surface of seid die on its cutting stroke and farther away therefrorn on its return stroke, and means 'f0i varying Ehe position cf Ehe whole machine, substanbially as shown and described.
